I know 8 trans people well and many more as acquaintances. The 8 people I know well range from being an old childhood friend, to coworkers, to students, to neighbors.
I'm mostly aware that they are trans at all due to the increase in anti-trans laws and blatant transphobia in the US. Were it not for that? I might not know or even care. I worry about them.
In each case the fact that they are trans is one of the less interesting things I know about them.
